� possible by UniMod GSM only
� At the end of every programming the settings have to be saved permanently
using the at&w command. This ensures that the parameters are restored
after power failure.
Example (e.g. UniMod GSM or Metcom T M..):
� Establish connection PC to modem (e.g. using the parametering adapter).
� Insert SIM card.
� Switch on Metcom T M../UniMod GSM.
� Start terminal program and set data rate correctly.
The modem does not reply to a simple AT command by default. In order to
test communication you have to use a command which results always in an
answer (e.g. ATI or AT&V). This should give an readable output on your
screen.
� Input AT&F to restore factory settings. Modem should reply OK.
� Set data rate of your terminal program to 19200 Baud and data format to
8N1.
� Ask modem for PIN status: Input AT+CPIN? Possible answers are:
+CPIN: SIM PIN PIN not active; enter PIN (see below)
+CPIN: READY PIN active
� Enter PIN: AT+CPIN="1234" (if PIN=1234). Modem reply: OK
� Unlock PIN: Enter AT+CLCK="SC",0,"1234". Modem reply: OK
� Check GSM network operator ("bearer"): Enter: AT+COPS?
Possible answers are:
